An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and use it for some service different from an Internet site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you could specify an Internet Protocol the domain name will use and the port, which will be used to connect to the remote server. Moreover, in case you have numerous SRV records for the very same service, you are able to set various priorities and weights for every single one of them, so you can distribute the load between many machines. Such a record allows you to use the same domain or subdomains under it with different companies, so you can employ it for various purposes even if you are unable to get all of the services from a single provider.
